Although not very well sign posted, you can subscribe (RSS Feed) to individual categories. This is good if you want say MS Help news but dont care about my family postings.
Notice that when you click on the category MS Help (Categories section of the side bar), you view just the MS Help related posts (and its sub-categories Vista AP, HTML Help, WinHelp etc).
Notice too that the URL http://weblog.helpinfo.eu/category/ms-help/ in your browser address bar now contains the category as a subfolder.
If you put the „/?feed=rss2“ at the end of the URL you now have an RSS feed for just MS Help http://weblog.helpinfo.eu/category/ms-help/&feed=rss2 (and its sub-categories).
Paste that into your IE7 browser or favorite news reader and you can now subscribe to just that section of the blog.
